1.查看镜像

输入命令crictl images ls查看镜像

[root@master1 spider]# crictl images ls

2.导出镜像

[root@master1 ~]# ctr image export b.tar dc6f84c32585f
WARN[0000] DEPRECATION: The `mirrors` property of `[plugins."io.containerd.grpc.v1.cri".registry]` is deprecated since containerd v1.5 and will be removed in containerd v2.0. Use `config_path` instead.
ctr: image "dc6f84c32585f": not found
[root@master1 ~]# ctr image export b.tar registry.cn-beijing.aliyuncs.com/kubesphereio/cni:v3.27.4
WARN[0000] DEPRECATION: The `mirrors` property of `[plugins."io.containerd.grpc.v1.cri".registry]` is deprecated since containerd v1.5 and will be removed in containerd v2.0. Use `config_path` instead.
ctr: image "registry.cn-beijing.aliyuncs.com/kubesphereio/cni:v3.27.4": not found

可以看到提示镜像不存在,根据crictl命令查看到镜像是存在的

搜了一下两者的区别

ctr：containerd本身的CLI
crictl ：Kubernetes社区的专门CLI工具

Kubernetes的镜像是放在k8s.io的namespace下的

ctr -n k8s.io image export b.tar 镜像名称:版本号

[root@master1 ~]# ctr -n k8s.io image export b.tar registry.cn-beijing.aliyuncs.com/kubesphereio/cni:v3.27.4
WARN[0000] DEPRECATION: The `mirrors` property of `[plugins."io.containerd.grpc.v1.cri".registry]` is deprecated since containerd v1.5 and will be removed in containerd v2.0. Use `config_path` instead.
[root@master1 ~]# ls

[root@master1 ~]#

可以看到镜像已经导出
